<p class='vspace'></p><h2>delayMicroseconds()</h2>
<h4>Description</h4>
<p>Pauses the program for the amount of time (in microseconds) specified as parameter.  There are a thousand microseconds in a millisecond, and a million microseconds in a second.
</p>
<p class='vspace'></p><p>Currently, the largest value that will produce an accurate delay is 16383.  For delays longer than a few thousand microseconds, you should use delay() instead.
</p>
<p class='vspace'></p><h4>Syntax</h4>
<p>delayMicroseconds(us)
</p>
<p class='vspace'></p><h4>Parameters</h4>
<p>us: the number of microseconds to pause (<em>unsigned int</em>)
</p>
<p class='vspace'></p><h4>Returns</h4>
<p>None
</p>
<p class='vspace'></p><h4>Example</h4>
<pre> 
int outPin = 14;                 // digital pin 14

void setup()
{
  pinMode(outPin, OUTPUT);      // sets the digital pin as output
}

void loop()
{
  digitalWrite(outPin, HIGH);   // sets the pin on
  delayMicroseconds(16383);     // pauses for 16383 microseconds      
  digitalWrite(outPin, LOW);    // sets the pin off
  delayMicroseconds(16383);     // pauses for 16383 microseconds      
}

</pre>
<p class='vspace'></p><p>configures pin 14 to work as an output pin. It sends a train of pulses with 32766 microseconds period.
</p>
<p class='vspace'></p><h4>Caveats and Known Issues</h4>
<p>This function works very accurately in the range 3 microseconds and up. We cannot assure that delayMicroseconds will perform precisely for smaller delay-times.
</p>
<p class='vspace'></p><p>Currently, delayMicroseconds() no longer disables interrupts.
